OBJECTIVE: Cerebral venous infarction (CVI) is a rare vascular disease, most commonly caused by cerebral venous thrombosis, which leads to brain tissue ischemia and anoxia, followed by necrosis, hemorrhage, and infarct formation. CVI has diverse clinical manifestations; thus, diagnosis is very difficult, and the prognosis is poor. The goal of this study is to provide a theoretical basis for treating patients suffering from CVI combined with high intracranial pressure. To this end, a rabbit model of CVI was established by placing a recoverable epidural sacculus...

Vascular involvement in Late Onset Pompe Disease, glycogen storage disease type II characterized by limb-girdle muscle and diaphragmatic weakness, is well documented. Abnormalities of posterior cerebral circulation have mostly been reported, whereas there are also cases of associated extracerebral arteriopathy. We report the case of a 42-year-old man diagnosed with LOPD a year after renal infarct due to renal artery fibromuscular dysplasia. We propose that the association of LOPD and arteriopathy should always be considered in clinical practice...

Patients suffering from acute intractable vomiting are usually treated in the Gastroenterology department. The causes of acute intractable vomiting range from acute pancreatitis and acute intestinal obstruction to cardiac causes like acute myocardial infarction and neurological causes like posterior circulation stroke. However, most of the underlying causes of acute intractable vomiting also produce other telltale signs/symptoms. Rarely, isolated acute intractable vomiting may be the initial symptom of a recurrent neurological syndrome of neuromyelitis optica spectrum disorder (NMOSD)...

The basilar artery (BA), as a reference vessel for laboratory investigations of cerebral vasospasm (CVS) in many experimental models, warrants a sufficient blood supply despite hemodynamic changes during CVS. In a prospective evaluation study, we analyzed  patients who were admitted to our department with subarachnoid hemorrhage (SAH) for the occurrence and sequelae of CVS. Specifically, we sought to identify patients with CVS of the BA. As per institutional protocol, all patients with CVS detected in the posterior circulation had magnetic resonance imaging (MRI) examinations instead of CTA...

Reversible cerebral vasoconstriction syndrome is characterized by thunderclap headache and multifocal cerebral vasoconstriction. Cerebral vasoconstriction is reversible, and most cases have good prognosis. However, clinical outcome is possibly severe when it is complicated by stroke, yet detailed reports on such a case are few. We experienced a case of severe reversible cerebral vasoconstriction syndrome in a 32-year-old woman with medical history of preeclampsia 3 years prior. She presented with sudden sharp headache followed by altered mental status and vasoconstriction of the bilateral posterior cerebral arteries...

This article reports the surgical management of a 3-month-old girl with Saethre-Chotzen syndrome, who presented with bicoronal synostosis and a large midline sinus pericranii with abnormal cerebral venous drainage via scalp veins. Raised intracranial pressure was demonstrated on monitoring, indicating the need for calvarial expansion necessitating a coronal access incision. A 2-staged delayed raising of the coronal flap was performed to reduce the potential risk of cerebral venous infarction. Monitoring for clinical sequelae and a computerised tomography venogram followed each of these procedures, demonstrating successful redirection of the venous drainage of the brain posteriorly...

Context: We describe a case of unilateral posterior upper cervical spinal cord infarction and propose a pathophysiologic mechanism causing this lesion after vertebral artery endovascular intervention. Findings: A 70-year-old male presented with subacute onset of left hemibody sensory changes and gait instability following a left vertebral angioplasty procedure. MRI cervical spine revealed upper posterior cervical spinal cord infarction (PSCI). After 3 months patient had substantial improvement of his symptoms...

Introduction: Cerebrovascular disease is the second most common cause of central nervous system involvement in cancer patients after metastases. Procoagulant substances secreted by tumour cells, cancer therapy, and embolus from tumour have been implicated in ischemic stroke (IS) in cancer patients. Methods: Four thousand twenty patients with IS were prospectively recorded to the Istanbul Medical School Stroke Registry from August 1997 to May 2016. Ninety-two patients with IS and cancer and 3928 IS patients without cancer constituted the two groups...

BACKGROUND: Headache is a common feature in acute cerebrovascular disease but no studies have evaluated the prevalence of specific headache types in patients with transient ischemic attacks (TIA). The purpose of the present study was to analyze all headaches within the last year and the last week before TIA and at the time of TIA. METHODS: Eligible patients with TIA (n = 120, mean age 56.1, females 55%) had focal brain or retinal ischemia with resolution of symptoms within 24 h without presence of new infarction on MRI with DWI (n = 112) or CT (n = 8)...

INTRODUCTION: In the United States, the number of posterior cervical fusions has increased substantially. Perioperative neurological complications associated with this procedure, such as spinal cord and peripheral nerve injuries, can have significant effects on patient health. As such, we examined the impact of perioperative neurological deficits on mortality in patients undergoing posterior cervical fusion. The secondary aim was to understand the risk factors for perioperative neurological complications...

The occlusion of the artery of Percheron (AOP) is a rare condition that causes bilateral thalamic ischemic stroke with or without midbrain involvement. It happens as a result of an anatomical variant of the diencephalic irrigation, in which the thalamic paramedian arteries arise from a common trunk from the posterior cerebral artery (PCA), which generates a clinical syndrome characterized by bilateral vertical gaze palsy, memory impairment and hypersomnia. In this case, we report a 62-year-old woman admitted to the emergency room with altered mental status, mainly somnolence...

Posterior reversible encephalopathy syndrome (PRES) or leukoencephalopathy syndrome was introduced into clinical practice in 1996 by Hinchey et al ., to describe unique syndrome, clinically expressed during hypertensive and uremic encephalopathy, eclampsia, and immunosuppressive therapy. Hyperperfusion with resultant disruption of the blood-brain barrier results in vasogenic edema, but not infarction, most commonly in the parieto-occipital regions. The severity of this clinical symptom varies. For example, the visual disturbance can manifest as blurred vision, homonymous hemianopsia, or even cortical blindness...

RATIONALE: Splenic artery pseudoaneurysm induced by benign gastric ulcer is extremely rare and can lead to a fatal clinical situation. To the best of our knowledge, there are only five cases in the literature review. Therefore, it can be a diagnostic challenge for radiologists and clinicians because of rare incidence. PATIENT CONCERNS: The patient visited our hospital due to melena and dizziness. DIAGNOSES: The patient showed a huge ulcer and an exposed vessel in the posterior wall of the gastric high body during endoscopy...

A 65-year-old woman presented with sudden bilateral visual loss of recent onset. She was recently diagnosed with multiple acute stroke syndrome for which she was commenced on antiplatelet therapy. Funduscopic examination revealed bilateral inferotemporal retinal artery occlusions. The recent history of multiple cerebral infarcts combined with the current ocular findings prompted a transoesophageal echocardiogram which successfully revealed caseous calcification of the mitral valve annulus as the source of the numerous sequential emboli, a finding which the conventional transthoracic echocardiogram had failed to disclose as a result of suboptimal image quality...
